De la O Levy was clear in stating that the issue is not linked to the U.S. embargo. This daily theft of transformer oil is a major issue. On April 27, oil theft at a substation in Jagüey Grande, Matanzas, left 4,429 homes, along with a hospital, a clinic, and a hygiene center, without power. In Guerrita, Mayarí, Holguín, over 400 customers were without electricity for 29 days following the oil theft from a substation. In May, De la O Levy admitted that Cuba lacked reserves of fuel oil and diesel to generate electricity, relying instead on accompanying gas and domestic crude oil.
